Caudal cut square, with rounded angles or slightly emarginate. Free portion of the tail from one and a half to twice as long as high at its base. Scales absent. Colours : marbled or irregularly blotched and spotted with brown; fins also more or less spotted. Hub. Cashmere Lake. 21. NEMACHEILUS RUPICOLA. Schistura rupicola, M'Clelland, Journ. Asiat. Soc. of Beng. vii. pl. 55. fig. 3, and Ind. Cypr. p. 309, pl. 57. f. 3. The Cashmere species are almost or quite destitute of scales, and otherwise agree with M'Clelland's fish. It may, however, be questionable whether N. montana, M'Clelland, and some other recognized species are not merely varieties of one form, as the variations in one locality and also changes with age are very great. NEMACHEILUS MICROPS*. Cobitis microps, Steind. Verh. z.-b. Ges. Wien, 1866, p. 794, t. xiii. f. 3. Nemacheilus microps, Gunther, Cat. vii. p. 357. This species is entirely destitute of scales. It was obtained by Dr. Stoliczka in Tibet, on his first journey ; but no specimens exist amongst the Yarkand collection. If we examine the localities whence the fishes which form this collection were procured, omitting the Cashmere examples, we find as follows :- N a m e of species.
